The mysterious life of Pythagoras

Pythagoras is an ancient Greek mathematician. I think you have heard the term ”Pythagorean theorem” (three squares theorem). It is a story that comes out in elementary geometry, and it can be applied in various ways. The same Greek Democrates has a cheerful image, while the image of Pythagoras is dark and mysterious. They said Pythagoras to have been born around Turkey. and,

After that, there is not much information left in modern times. The sect, which they said to have been organized by Pythagoras in the first place, strictly prohibited the leakage of stories within the organization to the outside. Since it is actually a secret society, he was punished when he violated the rules and had pushed into the sea.

No matter how many times I heard it, it seemed  for me like a cruel story, and people of that era couldn’t swim, so it was equivalent to the death penalty. If a believer who happened to be a fisherman had been floating, they would have stabbed  with a stick from the ship. Since it was such a secretive cult, we could not see the portrait of Pythagoras, and there was no manuscript.

For the Pythagoras’s era is extreemly old. What we can get a glimpse of is the story and copyrighted work of the disciple who has lost his connection with the cult in the secondary information. According to such secondary information, Pythagoras traveled to Egypt and India when he was young, and he deepened his knowledge about geometry, astronomy, arithmetic, ratios, religious esoterics, Zoroastrianism, and so on.

Uniqueness of Pythagoras

A characteristic of Pythagoras’s thinking was the advocacy of the objective fact that “every event has a number inherent in it.” Certainly, if we summarize it later, there is a mass in everything at that time, there is a state such as “solid / gas / liquid”, there is a volume occupied in space, and there is a temperature at that time.

Using these various parameters, later scholars will systematize and systematize their relationships, but that is a later story. Pythagoras created the ground for such discussions. I think it was a huge step forward. Pythagoras has shown that he also plays a number of major roles in the world of music and astronomical.

Activities and consequences of the Pythagorean school

Pythagpras had said to have studied geometry and religious esoterics in Egypt, gained knowledge of arithmetic and proportions in Phoenicia, and studied under a Zoroastrian priest.

After spending such training and training, Pythagpras had based in the Italian Peninsula. Pythagoras had attracted various people with words and deeds, and eventually gathers many disciples and organizes an organization They called the Pythagorean School (Pythagorean Church). There was a time when a patron had formed in this organization, but some people opposed the organization, and they said that Pythagoras was eventually rioted and killed.
